Continued with assembling the window frames, frustrated by the poor quality of these. I could have made a better job for sure. The first needed adjustment to bring the droplight slides into line. The second one I worked on turned out to be better dimensionally and need little fettling. These are a long job requiring many holes to be drilled and trial assembly. I completed two by the end of Friday and started on a third, which was largely complete by the end of the week.
